“…Indeed, the WHO guidelines in force recommend an annual frequency of mass distribution of praziquantel in areas of high endemicity against a frequency of treatment every two years for areas of medium prevalence [12]. This trend is con rmed by the results of Malian Schistosomiasis Control Program which showed a signi cant reduction from 26.4 to 6.8% in 1999; 14.2 to 4.8% in 2004 and 5.4 to 2.4% in 2010 [13] and also to Sotuba where it went from 86.77; 100 and 94% respectively in 2005, 2008, 2009 to 8.7% in 2010 [14].…”

Background - Schistosomiasis is a water-based parasitic disease caused by blood flukes of the genus Schistosoma. Mass Drug Distribution (MDD) with Praziquantel is periodically recommended in schistosomiasis-endemic countries to prevent morbidity. In Mali, schistosomiasis still remains endemic, especially in Senegal and Niger rivers basin, although the strategy has been adopted since 2005. Our study aimed to assess the impact of annual school-based MDD. Materials and methods – The study was conducted at twelve sentinel sites across Kayes and Koulikoro regions. A cross-sectional study design was performed in April 2018 after four-or five-years post treatment with praziquantel (PZQ) depending on the statute of sites. At baseline (2014-2015) and for the control year (2018), 734 (386 boys and 347 girls) and 1708 (844 boys and 864 girls) school children of 7-14 years of age, were successfully examined respectively. Infections with Schistosoma haematobium and S. mansoni were diagnosed with the urine filtration and the Kato-Katz method respectively. Results – From eight schools treated in 2014, the four annual rounds of MDD with PZQ were associated with a significant decrease in S. haematobium prevalence in five sites (p<0,001) and a significant increase in one site (p<0,001). Of them, the prevalence of high-intensity (≥50 eggs/10mL of urine) significantly decreased in four previous sites but not in Diakalele where it increased ((p<0.001). In all the four sites treated in 2015, S. haematobium prevalence increased significantly in Kokoun and Samaya (P<0.05). The heavy infection increased slightly in Dougourakoro and Samaya (P>0.05). The prevalence of S. mansoni significantly decreased in three sites (p<0.001), increased in three and remains zero in the six others sites. Conclusion – Our findings show that five of the twelve sentinel sites have achieved the criterion of elimination of schistosomiasis due to Schistosoma haematobium as a major public health problem (Prevalence of heavy infection <1%); three have achieved the criterion of morbidity control (Prevalence of heavy infection <5%), whereas two sites remain confined below the control criterion. These results call for a strong improvement in the therapeutic coverage associating, education and provision of safe water, sanitation and hygiene to interrupt the transmission cycle of the schistosome.

“…Au Mali, la schistosomiase a fait l'objet de beaucoup d'études sur l'épidémiologie (Tandina et al, 2016), la variabilité génétique, le degré de l'intensité de l'infection et enfin sur la morbidité ; surtout dans les zones endémique. La Schistosomiase est endémique dans de nombreuses régions du pays (Traore et al, 2007 ;Clements et al, 2008).…”

, la schistosomiase est un problème de santé publique comme dans tous les 42 pays africains sur 76 concernés dans le Monde, avec 230 millions de personnes infectées sur 800 millions de personnes exposées et plus de 800 000 décès annuels. L'objectif de cette étude était de comprendre les complications de la schistosomiase par des investigations parasitologue, échographique et clinique dans trois zones endémiques à traitement de masse répété de la région de Ségou au Mali. Les sites d'étude : Guénidanga, Kalabougou et M'Pèba sont situés le long du fleuve Niger. Le diagnostic était basé sur la filtration de l'urine, le KATO-KATZ des selles, l'examen physique, la réplétion vésicale et l'échographie abdominopelvienne. Sur les 327 sujets de l'étude, 50,80% d'individus infectés avaient au plus 5 ans suivie de ceux ≥24 ans avec 22%. La charge ovulaire était plus élevée chez les sujets de 5 à 14 ans. Malgré un traitement de masse répété, des complications ont engendré d'importantes lésions rénales et vésicales chez les sujets masculins. La persistance de la schistosomiase humaine pourrait être due soit à une probable réinfection rapide, soit à une fluctuation de la population des mollusques dans ces zones.

“…Twenty percent of pediatric patients with cerebral malaria in Mali reported headaches [ 42 ]. Also in Mali, a study looking for schistosomiasis prevalence also found 27.2% of participants had abdominal pain and 23.2% headaches [ 43 ]. A large study in Kenya described a 51.1% prevalence of abdominal pain in children with cryptosporidiosis [ 44 ].…”

Chronic Pediatric Pain in Low- and Middle-Income Countries

Chronic pain is a serious health concern and potentially debilitating condition, leading to anxiety, depression, reduced productivity and functionality, and poor quality of life. This condition can be even more detrimental and incapacitating in the pediatric patient population. In low- and middle-income countries (LMICs), pain services are often inadequate or unavailable, leaving most of the world’s pediatric population with chronic pain untreated. Many of these children in LMICs are suffering without treatment, and often die in pain. Awareness and advocacy for this population must be prioritized. We reviewed the available literature on the chronic pediatric pain burden in LMICs, barriers to treatments, and current efforts to treat these patients.
